Problems solved by technology

However, it is difficult for the refractive lens to break through its physical threshold limit when designing at a lower thickness
In addition, due to the problem of the accuracy of the parts, the assembly of the overall module often causes poor optics due to the deviation of the parts.

Abstract

A center point of the curve corresponding to the light emitting diode chip is a zero point of y-z coordinate axes. z is a variable of vertical axis of the curve. y is a variable of horizontal axis of the curve. ai is a constant coefficient in a term of ith degree. 3<n<=6.

Description

technical field [0001] The invention relates to a light emitting diode packaging structure, and in particular to a light emitting diode packaging structure with a lens. Background technique [0002] Since Light-Emitting Diodes (LEDs) have the advantages of long life, small size, low vibration, low heat dissipation, and low energy consumption, LEDs have been widely used in devices such as indicator lights or home light sources. In recent years, with the development of multi-color gamut and high brightness, light-emitting diodes have been applied in various display devices, illumination devices, and the like. [0003] The light-emitting properties of the device will affect the display performance of the product. [0004] For example, a liquid crystal display device uses a backlight module. The direct-lit backlight module can be used with LED light sources and lenses. [0005] One solution of the direct-type light-emitting module is to use a reflective lens, which can direct...
